ABSD, or Additional Buyer’s Stamp Duty, is a tax imposed by the Singapore government on individuals or entities purchasing residential properties in the country. This tax is in addition to the standard Buyer’s Stamp Duty and is aimed at curbing excessive demand and speculation in the real estate market. The amount of ABSD payable varies depending on the buyer’s residency status, the number of properties owned, and the type of property being purchased. ABSD serves as a measure to promote a stable and sustainable property market in Singapore.
